Description

Technical Field

[0001] This utility model relates to the field of circuit board installation and disassembly, and in particular to a detachable relay control circuit board for an air conditioner outdoor unit. Background Technology

[0002] Air conditioners, as essential devices for regulating indoor temperature in modern life, are widely used in homes, commercial spaces, and other settings. The proper functioning of the outdoor unit plays a crucial role in the overall performance of the air conditioner, and the relay control circuit board, as a core component of the outdoor unit's circuit system, directly impacts the air conditioner's efficiency and stability through its performance and ease of installation and maintenance.

[0003] Currently, most commercially available relay control circuit boards for detachable air conditioner outdoor units are installed using bolts. During installation, screwdrivers and other tools are needed to tighten the bolts, which is not only cumbersome and time-consuming, but also prone to problems such as stripped bolts and damage to the circuit board due to improper tool use. Similarly, during disassembly and maintenance, tools are needed to loosen the bolts; if the bolts are rusted or stuck, disassembly becomes even more difficult, reducing maintenance efficiency. Furthermore, frequent bolt-based fixing and disassembly can easily cause wear on the circuit board mounting holes, affecting installation stability and posing safety hazards. Therefore, this application proposes a detachable relay control circuit board for air conditioner outdoor units to address these technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable relay control circuit board for an air conditioner outdoor unit. A plug is inserted through a socket into a fixing rod. The inner wall of the fixing rod pushes a rotating rod, compressing a spring. Once the rotating rod enters a limiting groove, spring one causes it to rotate outwards and is stopped by a stop block. Simultaneously, spring two compresses the rear end of the plug. After release, spring two pushes the plug, causing a protrusion on the rotating rod to engage with the front end of the rotating groove, preventing the rotating rod from rotating inwards and ensuring the plug's stability. Compared to traditional bolt fixing, the circuit board can be installed without tools, and the multiple structural elements ensure installation stability. Disassembly is simple: just press the plug backwards to disengage the protrusion from the front end of the rotating groove, allowing the rotating rod to rotate inwards. Then, push it back into the plug to remove it. The entire process is straightforward, significantly reducing disassembly difficulty. This aligns with the installation process, making the installation and disassembly of the circuit board convenient and improving operational efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A detachable relay control circuit board for an air conditioner outdoor unit includes a circuit board body. Each of the four corners of the circuit board body has a socket, and each socket contains a plug. The outer wall of each plug has a rotating groove, and the inner wall of each plug has an ejector assembly. A fixing rod is located at the rear end of each socket. A base plate is slidably connected to the inner wall of the fixing rod. A second spring is located at the rear end of the base plate. One end of the second spring is connected to the rear side of the base plate, and the other end of the second spring is connected to the inner wall of the rear end of the fixing rod.

[0006] Furthermore, the ejection assembly includes a rotating rod fixedly connected to the inner wall of the plug, a rotating rod rotatably connected to the outer wall of the rotating rod, and a protrusion fixedly connected to the end of the rotating rod away from the rotating rod.

[0007] Furthermore, a spring is provided on the inner wall of the plug, one end of the spring being connected to the inner wall of the plug, and the other end of the spring being connected to the rotating rod.

[0008] Furthermore, both the upper and lower ends of the rotating rod are fixedly connected to stop blocks, and the stop blocks are located inside the plug to limit the rotation of the rotating rod.

[0009] Furthermore, a limiting groove is formed on the outer wall of the fixing rod, and the size of the limiting groove is larger than the size of the rotating rod. The limiting groove is used to engage with the protrusion.

[0010] Furthermore, the length of the rotating groove is greater than the length of the rotating rod, and the width of the rotating groove is adapted to the width of the rotating rod, so as to facilitate the rotation of the rotating rod.

[0011] Furthermore, the outer diameter of the plug is smaller than the inner diameter of the fixing rod, so as to facilitate the insertion of the plug into the fixing rod.

[0012] Furthermore, the rear end of the fixing rod is fixedly connected to the inner wall of the outdoor unit of the air conditioner.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a plug is inserted into a fixing rod through a plug hole. The inner wall of the fixing rod pushes the rotating rod to compress the first spring. After the rotating rod enters the limiting groove, the first spring causes it to rotate outward and is limited by the stop block. At the same time, the rear end of the plug compresses the second spring. After the spring is released, the second spring pushes the plug to make the protrusion of the rotating rod engage with the front end of the rotating groove, preventing the rotating rod from rotating inward and ensuring the plug is stable. Compared with traditional bolt fixing, circuit board installation can be completed without the aid of tools, and the installation stability is guaranteed by the cooperation of multiple structures.

[0014] 2. In this utility model, during disassembly, simply press the plug backward to disengage the protrusion from the front end of the rotating groove, and the rotating rod can then rotate inward. Afterward, push it into the plug to remove the plug. The whole process is simple and greatly reduces the difficulty of disassembly. It corresponds to the installation process, realizes the convenience of circuit board body installation and disassembly, and improves operation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1-3This utility model provides an embodiment of a detachable relay control circuit board for an air conditioner outdoor unit, comprising a circuit board body 1. Each of the four corners of the circuit board body 1 has a socket 4. When installing the circuit board body 1, a plug 2 is inserted into the socket 4, and then the plug 2 is inserted into a fixing rod 3. The socket 4 contains the plug 2, and the outer wall of the plug 2 has a rotating groove 7. The rotating groove 7 is provided to facilitate the rotation of a rotating rod 5, allowing the rotating rod 5 to fully rotate into the plug 2. A rotating rod 10 is fixedly connected to the inner wall of the plug 2, and a rotating rod 5 is rotatably connected to the outer wall of the rotating rod 10. The rotating rod 5 can rotate around the rotating rod 10 as a rotation point. A protrusion 13 is fixedly connected to the end of the rotating rod 5 away from the rotating rod 10. The protrusion 13 allows for... The rotating rod 5 engages with the front end of the limiting groove 6, thus preventing the rotating rod 5 from being rotated into the plug 2 after installation, thereby ensuring that the rotating plate 5 can always limit the plug 2. A fixing rod 3 is provided at the rear end of the insertion hole 4. A base plate 11 is slidably connected to the inner wall of the fixing rod 3. A spring 12 is provided at the rear end of the base plate 11. One end of the spring 12 is connected to the rear side of the base plate 11, and the other end of the spring 12 is connected to the inner wall of the rear end of the fixing rod 3. During the process of the plug 2 being inserted into the fixing rod 3, the rear end of the plug 2 will also compress the spring 12 through the base plate 11. When the rotating rod 5 rotates into the limiting groove 6, releasing the plug 2 will allow the spring 12 to return to its original state and push the plug 2 forward a certain distance through the base plate 11.

[0019] Reference Figure 1-3 The inner wall of the plug 2 is equipped with a spring 8. One end of the spring 8 is connected to the inner wall of the plug 2, and the other end is connected to the rotating rod 5. When the inner wall of the fixed rod 3 pushes the rotating rod 5 into the plug 2, the rotating rod 5 can compress the spring 8. When the rotating rod 5 disengages from the inner wall of the fixed rod 3, that is, when the rotating rod 5 matches the limiting groove 6, the spring 8 returns to its original position, pushing the rotating rod 5 out of the plug 2 and causing it to rotate into the limiting groove 6. Both the upper and lower ends of the rotating rod 5 are fixedly connected to a stop block 9, which is located inside the plug 2 to limit the rotation of the rod 5 and prevent it from rotating out completely. The outer wall of the fixed rod 3 has a limiting groove 6, and the size of the limiting groove 6 is larger than the size of the rotating rod 5. The limiting groove 6 is used to engage with the protrusion 13 and to limit the rotation of the rod 5 to prevent the plug 2 from being pulled out. The length of the rotating groove 7 is greater than the length of the rotating rod 5, and the width of the rotating groove 7 is adapted to the width of the rotating rod 5 to facilitate the rotation of the rotating rod 5. The outer diameter of the plug 2 is smaller than the inner diameter of the fixing rod 3 to facilitate the insertion of the plug 2 into the fixing rod 3. The rear end of the fixing rod 3 is fixedly connected to the inner wall of the outdoor unit of the air conditioner.

[0020] Working principle: When installing the circuit board body 1, firstly, a plug 2 is passed through the socket 4 and inserted into the fixing rod 3. During the insertion process, the inner wall of the fixing rod 3 pushes the rotating rod 5 inward, and the rotating rod 5 compresses the spring 8. When the rotating rod 5 moves into the limiting groove 6, the spring 8 returns to its original position, allowing the rotating rod 5 to rotate outward from the plug 2. The stop block 9 limits the rotation of the rotating rod 5, preventing it from rotating out completely. During the insertion of the plug 2, the rear end of the plug 2 also compresses the spring 12 through the base plate 11. When the rotating rod 5 rotates into the limiting groove 6, releasing the plug 2 allows the spring 12 to return to its original position, and the base plate 11... Pushing the plug 2 forward a certain distance causes the protrusion 13 on the rotating rod 5 to engage with the front end of the rotating groove 7, thus preventing the rotating rod 5 from rotating inward into the plug 2 and ensuring that the rotating rod 5 remains within the limiting groove 6. This effectively limits the position of the plug 2. Compared to the traditional bolt-fixing method, the circuit board body 1 can be installed without tools, while still ensuring installation stability. For disassembly, simply press the plug 2 backward a certain distance so that the protrusion 13 disengages from the front end of the rotating groove 7, allowing the rotating rod 5 to rotate inward into the plug 2. Then, push the rotating rod 5 into the plug 2 to remove it. The entire installation and disassembly process is simple and easy to operate.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
